It has been confirmed that an anime adaptation for Drifters is in production. For those who don't know Drifters' mangaka is the same as that of Hellsing, Kouta Hirano, and surely is similar to it in quite some ways.
An OAV for it was also released back in 2012.
Sypnosis:
Shimazu Toyohisa, whilst involved at the Battle of Sekigahara, manages to mortally wound Ii Naomasa, but is critically wounded in the process. As he walks from the field broken and bleeding, Toyohisa finds himself transported to a corridor of doors, where a bespectacled man at a desk waits for him. This man, Murasaki, sends Toyohisa into the nearest door where he wakes up in another world. There, Toyohisa meets other great warriors from past and future like him who have been transported as well, to be part of a group known as "Drifters."
